Title: Position indicator
Inventor: MURAKAMI AZUMA
IPC: G06K11/06
Filed: 1989-08-08
Abstract: PURPOSE:To switch the processing mode by varying the degree of attenuation of an induction voltage by using a frequency changing circuit containing a resonator and a frequency changing circuit containing no resonator by switching them by a switch. CONSTITUTION:When a radio wave of a prescribed frequency is sent out of a tablet, an induction voltage is generated in a circuit constituted of a main circuit 18 and a first frequency changing circuit 19 or a second frequency changing circuit 20. When the radio wave comes not to be sent out of the tablet, a current of a prescribed frequency flows through the circuit by electromagnetic energy accumulated in coil 3 and capacitors 10, 11 - 15 and 16, and a radio wave is transmitted. This current is decreased due to a loss in the circuit, but when a switch 9 is at the 9a side, since a resonator 17 is placed in the circuit, large energy is accumulated, and the attenuation is smaller than the case the switch 9 is at the 9b side. Accordingly, the mode can be discriminated.

Title: Summarized sentence generating system
Inventor: ONO KENJI
IPC: G06F17/27
Filed: 1990-08-02
Abstract: PURPOSE:To efficiently generate summarized sentences of high quality having a proper connection expression by extracting only important sentences in input sentences together with the context structure in accordance with the designated number of summarized sentences. CONSTITUTION:A connection relation judging part 4 refers to selection rules which are preliminarily registered in a rule part 5 and are peculiar to connection relations between sentences to judge whether one or both sentences should be abandoned or not in accordance with the structure, which indicates the context structure generated by a tree structure, by corange marking indicating the connection relations among plural sentences. If a sentence to be abandoned in found, information of this sentence is abandoned from the tree structure. Sentences of high importance left unabandoned are joined in accordance with the tree structure to obtain summarized sentences. Thus, summarized sentences of high quality where connection relations among plural sentences are clear are effectively generated.

Title: Multiple reflection type high sensitivity measuring apparatus
Inventor: MURAISHI SHUICHI
IPC: G01J3/26
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain a spectrum with sufficient S/N ratio even for a thin film sample of several nm while ensuring high sensitivity by regulating the gap between the sample and a reflector thereby causing multiple reflection of a P-polarized infrared light made incident on the gap. SOLUTION: A thin film sample 1 is set on the surface of a metal 2 and a reflector 3 is disposed oppositely thereto through a gap of about 1mm and then a P-polarized infrared light is introduced at an angle into the gap. The incident infrared light advances while repeating multiplex reflection on the reflector 3 and the surface of sample 1 or metal 2 before leaving the opposite end. The sample 1 or reflector 3 is moved up and down to regulate the gap so that the infrared light can be reflected a plurality of times including once. At each reflection point, the electric vectors of incident and reflected lights are enhanced mutually to produce a strong steady wave which interacts with the molecules of thin film formed on the surface of sample 1 to cause strong absorption. Consequently, the absorption strength can be enhanced in proportion to the number of increased times of reflection.

Title: Combustion detector
Inventor: KASADA TOSHIO
IPC: F23N5/24
Filed: 1990-08-01
Abstract: PURPOSE:To enable verification of whether combustion is securely stopped on abnormal combustion, by providing an oxygen-deficiency action verifying means for verifying whether an oxygen deficiency discriminating part operates when abnormal combustion is carried out for a predetermined period of time by sending a signal to a combustion controlling part to forcibly change combustion quantity or the quantity of combustion air supplied. CONSTITUTION:When an oxygen-deficiency action verifying switch 15 is judged to be ON during combustion, a CPU 13b controls a pulse signal fed to an electromagnetic pump 7, thereby forcibly decreasing combustion quantity only, and starts an oxygen-deficiency action verifying timer. In the case of ordinary oxygen deficiency, a flame current is lowered to or below a reference value io; therefore, combustion is stopped, and an oxygen deficiency indication lamp in a display device 14 is turned ON. On the other hand, where failure exists in a combustion detecting part 3 or the like and a flame rod 9 makes contacts with a burner 6 or a current flowing to a resistor 12 is increased due to a leakage current or the like, a flame current greater than an actual current flowing through a flame is detected, so that the flame current is not reduced to or below the reference value io even on a decrease in the combustion quantity. When the flame current does not fall to or below the reference value io even after 20sec is counted by the timer, the status of failure is displayed on the display device 14, and the combustion is stopped.
